When the rest of the fans were all excited about the upcoming concert, the managing and preparation team were running helter-skelter to make sure that everything before and during the concert would run smoothly.
Due to previous experience, I had long learned to always have an air conditioning technician with me during the concert whether from where we are coming from or from the local air conditioning supplier.
It was sometimes better to get one from the local business because they would be more conversant with the existing infrastructure and the air conditioning installation. For this particular concert, I was fortunate enough to have a friend who was an ac workman in this town and he was a wizard when it came to an HVAC unit including any type of commercial air conditioning system. He would be in charge of the air conditioning maintenance and any air conditioning repair service that may be needed, he was also to have a colleague with him. He had assured me that his colleague was very good at his job and even knew more about air conditioning than he did. The changing and prep room for the artists were fitted with a ductless multi-split that was regulated by some ancient-looking dial thermostat which he assured me that it worked fine. There was no need for any new air conditioning equipment because thorough a/c service had made sure everything was in good condition. With that in check, I could relax a little but there were other things I needed to oversee and in truth, I could only relax when the concert was over and we were all back up heading back home.
